Will the end-game instances currently in the retail version of the game (Onyxia, MC, BWL, AQ20/40, ZG, Naxx) have the scaling difficulty found in the in the new instances like easy, Medium and hard modes or will they remain as is? Also, Will the loot in those instances be changed or modified at all for the expansion (other than the Combat rating change)

The reason I ask is because it seems to be a popular question among my guild members. The answer (be it yes or no) doesn’t matter to me either way, I’m looking forward to the new content…I would just like to know.

Upon the initial launch of the Burning Crusade, there will most likely not be any major changes to existing end-game dungeons. We would only change things if we found that the gameplay experience in those instances degraded to the point of being exploitive.

We don't have any immediate plans to change that content or the gear from those zones. Our focus right now is on making great 5, 10 and 25 person raid content that's new.

Hopefully, someday we can go back and revamp or add difficulty settings to old content but for the time being, most players will appreciate not feeling obligated to go to Molten Core for a few months =D And those who have never seen those zones, can experience them for the first time with an increased level cap.
